19. Study and Characterization of a Biomaterial: Animal Bone. Application to the Treatment of an Industrial Effluent

This work is a contribution to the search to limit the effects of this phenomenon, which has a problem of harmful effect on flora and fauna. The latter consists of the adsorption of an agricultural pesticide: Acetamiprid on a natural material: granulated activated carbon (GAC) and the granulated animal bone (cattle bone). This work is therefore a comparative study of the retention capacity of these natural biomaterials in order to limit the effects of this type of pollutants. Two natural adsorbents: industrial activated carbon and animal bone carbon: the latter is prepared in the laboratory. The results showed a similarity in the physicochemical characteristics of the two carbons: the maximum yield (or equilibrium of adsorption) is similar for both: equilibrium is obtained after seven days. The equilibrium isotherm shows that the Freundlich equation gave acceptable values for each animal coal and the industrial. The equilibrium isotherm equation check of Freundlich gave a values (n = 0.854; K = 1.746) for animal coal and (n = 0.985; K = 1.798) for industrial coal. The curves giving the adsorption isotherms show that these are of the Freundlich type.
